Is the service mode app in the thread below any use?
http://forum.xda-developers.com/showthread.php?t=2421161
Sent from my GT-I9505 using xda app-developers app
My GT-I9505 Rom Stock 4.4.2 ZTO(Brazil) had the same problem about signal problem.
Everytime i lock my phone (turning off the screen), by the time i light it on (lock screen), immediatelly my phone turns the signal to "No service".
In this time, i need to wait 1-2 minutes to the phone turns okay. Just wait.
I search for a lot of solutions and didn't find anything.
Notice too that the problem appears only network 2-3g. 4G didn't have the problem.
I solved this problem after Lollipop update. The problem simple dissapear!
(Sorry my bad english)
service problem
I'm not able to get any network /service at all on it only that circle with the line cross it.....
I tried everything possible I tried stock and custom roms, I factory reset it, I flashed all kinds of modems and still no luck, WiFi is working fine.... Anyone know what might be the problem?

sory, I was out at work
I updated it from kitkat to lollipop: so the version was d80220e when I atached into lg support tool it shows that an update is available which was d80230b
then when I updated it after rebooting the screen is gone crazy , no network and storage reduced to 10.6 after it was 32gb. now i believe there is a solution to this problem
if it is not d802 then what model is it
when opened the back cover it shows d801/d803 on the buttom in the imei service it says its a d802 and the back cover too.... what should I believe
refurbished

Nope. Only with direct EMMC write using a Medusa Box or other box that support this. No other way.

I have the same problem because I flashed a h815 rom on my h811. Since I have 2 weeks left on my warranty I will send it in and hope they will fix it for me. What are the chances they would fix a problem like this?

Had this on a g3 and it was possible to fix with software
Message tung kick to ask if it's possible.... He fixed my g3 within an hour a after I got nowhere in 8 hours
Check your S/N and if starts with 505-509, you'll have to get it fixed at the LG Service Center. They'll replace the MOBO of your G4

Because the number of tries to unlock it have been surpassed.. probably by the owner before me :S

OOHHH the phone . i tought you menat carrier.. i think its posible.. if you flash stock LG firmware..
now the question is is it really a at&t d800 phone?? some phone were refurbished and used different motherboards.. so phone says is d800 all aaround it and inside phone.. the only way to know uis by looking underneath the motherboard... this is if its been refurbished.. or was bought from ebay.. ect.... but if you want to try to go back to stock use this guide .. am not responsible for brick okey. read carefully. assuming you have a d800.. if falshed and all works correctly no ghost touch or touch screen having funny behaviour then you must check for variant.. if you want to go aheas and go back use this guide. read what you dont understand just ask, this will wipe everything in phone and leave it as new.. no traces.

The phone was advertised as refurbished. Should I just follow the guide you linked or should I first make sure which Model/Motherboard I am working with ?
Thanks alot for the help so far

First make sure what variant you really have.. then we can proceed with flashing..
you will know by looking underneath motherboard. pay no attention to other parts.

We need more information. What were you doing with your cellphone before this happened? Flashing something? If so, what?
Verify your phone is the model number you stated by removing the battery and checking the label.
Also make sure your pc drivers are good, that's one of the most common issues with Odin detection

Do you remember the steps you took to install it?
Something had to have gone really wrong for this to happen so I think maybe it's been flashed to the wrong place and has screwed something else up..
I doubt there's a way to repair this without the help of a qualified technician however
